My invention relates to a combinationV sand ump and bailer, and more particularly to a evice of that character for removln in the bottom o a well or dbris accumulated operation, the presrawings, wherein: .f l Fig. 1 is a vertical section of the lower end of a well hole partiallly cased, and in which a sand pump and bai er embodying my-mvention 1s shown in side elevation.

ortion device particularly illustrating the tralip valve and unloading door.

ig. 4 is a detail perspective view of the upper portion of the device lustrating attachment of the plunger rod to a sand line the line cover pla-te being shown detached from the rod. i

Fig. is a detail r- :ftive view ofthe lower end of the device :e the unloadoor open. meferring in detail to the drawin 1 designates a well hole with casm 2 and 3 the combination sand pump and a' er suspended in the well from a sand line 4.

The combination tool includes a tubular ody member 5, a bit element having a shank 6 attached to the lower end of the tubular body b a bayonet joint indicated at 7, and a pump gan-el 8 connected with the upper end of the bod member by a coupling 9 the seving presently described 1n detail. T e bayonet }oint connecting the bit element with the tubular body includes a sleeve having a reduced section l0 of a body eral parts particularly ilf s partially lined b member 11 forminga shoulder 12 which seats against the lower end of the tubular body 5, the sleeve ing permanenti attached to the tubular body member pre erably by rivets 13. Slots 14 in the lowerend oi. the body u member of the sleeve terminate 1n lateral duced neck 17 at the portion of the cnet joint.

A plate I8 slidable in grooves 19 and 20 in the bit element and body member 11 respective adjacent one of the slots serves as a latc tional position to securely connect the bit element with the tubular body member.

The bit element has an interior channel 2l communicating with the channel of the tubular body and upper end of the shank bit element, to form the bay- Van enlargement of the at the bottom of the bit element.
